Abstract: Telecommunication systems including a terminal, a switch and on Internet/Intranet having a memory for storing information blocks at locations defined by addresses, can be made more user-friendly by introducing a detector for detecting speech-recognition/non-speech recognition related parts in control signals originating from the terminal and defining the addresses or n response signals sent from memory to terminal and including said information blocks. A processor is coupled to the detector for routing, in dependence on the detection, routing (parts of) the signals to a server for either conversion of (parts of) the signals or for information purposes.

Abstract: In telecommunication systems including a terminal and a speech recognizer for vocal commanding, an indication signal originating from the terminal is detected, e.g., a telephone number dialed or a key signal or a vocal signal, or originating from an application located in the terminal or elsewhere in the network and in dependence of the indication signal a capacity parameter for the vocal commanding is adjusted, whereby a flexible capacity parameter is created for adjusting the available bandwidth between terminal and speech recognizer and/or for adjusting a processor capacity of terminal and/or speech recognizer, e.g., a sampling rate or a noise reduction being deactivated, as a result of which name dialing, command and control, and dictation can be done with the highest efficiency.

The proxy-server (2) retrieves at least one additional resource of modality requested within the multi-modal dialog. The proxy-server (2) composes a multi-modal interaction with the user (6) based on standard or extended hyper text mark-up language interactions with the client (6) and on the retrieved additional resources (71, 72, 73, 31, 32, 33).

Abstract: A method for establishing a digital communication link between an originating subscriber terminal and at least one called subscriber terminal, said method being better adapted to the transmission bandwidth used by a subscriber, has the following steps: First, a provisional link at a standard transmission rate from the originating subscriber terminal to the called subscriber is requested from a switching center. That provisional link is then established by the switching center. Next, a new, lower value for the transmission rate is selected by the originating subscriber terminal. That new value is then agreed upon with the switching center. Lastly, the latter switches the transmission rate of the provisional link over to the new, lower value, thus completing establishment of the communication link. The invention can advantageously be used in a telecommunications network, which for example operates according to the ISDN standard, to economize on transmission capacity and reduce call charges.

According to a method, terminal and browser application of invention at least one input and/or output processing application is provided for processing data related to the browser application, wherein multimodal meta tags from the mark-up language are interpreted for controlling the multimodal interactions and processing data of the multimodal interaction with respect to the multimodal meta tags.

Abstract: Distributed Speech Recognition (DSR) systems comprise terminals having a complex preprocessing unit and a network having a final processing unit. By leaving a Fast Fourier Transformation (FFT) together with a filtering function and a compression in said preprocessing unit by shifting both nonlinear transformation as well as a Discrete Cosine transformation (DCT) from said preprocessing unit into said final processing unit, where both follow decompression, said terminals are of a lower complexity. By using a MEL-filter (melody-filter) which preferably is adaptable, said low complex terminals are made more flexible.
